`genNextRect`, it takes the width and height of a rectangle as global parameters,

`gla2`and

`glb2`, and sets them to the next smallest golden rectangle. Note,

`genNextRect`assumes the

`gla2`and

`glb`are already a golden rectangle. This is done by taking one of the dimensions and dividing by the golden ratio, which will result in a smaller length. The

`flip`flag determine which dimension to shorten. It is the side with the longest length that is shortened. You will need to keep track of

`flip`such that, when

`genNextRect`is called, that the longest length of the rectangle is shortened. Alternatively, you could remove

`flip`entirely and change the condition in

`genNextRect`to select the longer edge. You may want to check that your rectangle's aspect ratio matches (or is close enough to) the golden ratio after calling

`genNextRect`.

After you have called

`genNextRect`you will need to draw it as demonstrated in the

`glBegin`/

`glEnd`block in

`display`. The assignment requires you continue drawing rectangles until the rectangles are too small to display. So, all that's left to complete the assignment is finding the first golden rectangle in the screen and a loop that calls

`genNextRect`and draws the new rectangle until the rectangle is too small to display.

P.S.

Don't panic.
